Lighting

The global illumination wasÂ done using HDRI. Â I made a render of the background and edited it withÂ a spherical effect. Â For the local lighting I usedÂ some VRayLight plane, boxes with a VrayLightMtl Emitter Light, and Direct Light to get the Caustic Effect in the aquarium glass and water.

Camera

I used a VrayPhysicalCamera with depth of field.

Post Production

UsingÂ Photoshop I corrected the colours, applied a Diffuse Glow and added a ray of light in the aquarium.
And here is the final image (Fig12).Â I hope you have enjoyed the Making of "Blue Bird Fishing". Â Thanks 3DTotal.com!
